To all whomltt mag/concern.' i 'i i Y y Be it known that I, VVAL'rnn E.Vniicnnmn,

i a citizen of the United States, and a resident;

of the city of Chicago, county of Cook, and` State of Illinois, haveinvented certain new and useful Improvements in Aeroplanes, of.l `whichthe following `is `a specification.

'. My invention relates to new and .usefull reference 4to theaccompanying drawing forming a part of` this specification, and in;

Figure 1 a longitudinal section of any aeroplaneembodying myvinvention,Fig. 2- is a section of the same taken on line 2 2 in Fig. l, Fig. 3 isan enlarged fragmentalr section of the controlling lever, its mountingand connections,` and Fig. 4: is an enlarged fraginental section takenon line 1 -st in Fig. 2.

illustrated in the drawing comprises a beaml 5 extending longitudinallyof the aeroplane and a keel 6 joined at its forward end to the forwardend of said beam, having a portion curved.downwardlyfrom said beam andits remaining portion parallel with said beam.

- A plurality of parallel spaced posts 7 eX- tend between said beam andkeel. Extending laterally of the beam 5 are ribs `8 upwardly curved andjoined at their inner ends to the beam 5. "Ihe outer ends of the ribs 8vare connectedby means of tie wires 9 to the keel 6. i i y In theforward part of the aeroplane is a vertical post 10 and a shaft 11journaled horizontally in said post. Mounted on the shaft 11 is apropeller mounting upon which is operatively mounted a propeller 12 `anda motor 13. The motor and propeller are fully described in myapplication above referred to, and do lnot form a part of the inventionclaimed in this application. y

On the shaft 11`is a lever 14 adapted to tilt the propeller 12 on shaft11. The lever 14 is connected by means of cables 15 with a controllerlever 16. Said controller lever is mounted for pivotal movement in aslot i y17 ofa post 18. Post 18 is provided with trunnions 19 which ai'e`1`ournaled `in the beam 5 and keel G, substantially as indicated.

At the rear end of the aeroplane is a vertical .post 20 slottedandprovided with a triangular rudder plane 21 secured therein and .adaptedto be operated by pivotal movenient of post 20. At the lower end of post2,0 `are arms 22 and the latter are connected to corresponding arms 23formed on the lower end of post 18 so that upon horizontal swingingoflever 16, corresponding pivotal `movement will be caused by post 2Oeffecting operation of the rudder plane 21.`

At the central portion of post 20 is provided a perforation in which isrotatably mounted a slotted shaft 2-1. In the slot of shaft 24: aremounted the two sections of a stabilizing plane `'lfhe sectionsofstabilizing plane 25 are triangular in shape,

one Asection being `disposed on each side of rudder plane 21, asindicated. The rear edges of both sections of `stabilizing plane .25 areconnected by means of cables 26 to the rearward end of controller lever16 passing" over pulleys 2S, said cables passing downt y wardly from therear edge of stabilizing rlhe preferred form `of construction as',

plane 25 to the lower part of the aeroplane frame in a manner to cause adownward pull on the rear portion of said stabilizing plane. The rearedges of the sections of stabilizing plane 25 are connected by means ofcables 29 to the forward end of controller lever 16 passing over pulleys30, the cables 29 passing upwardly from the rear edges of the sectionsof stabilizing plane 25 to the upper portion of the aeroplane frame andthence `to the controller lever 16 in a manner to cause upward movementof the rear portion of stabilizing plane 25 upon` operation of cables29.

In operation, to effect steering of the aeroplane, the controller lever16 is moved laterally, causing corresponding movement of the rudderplane 21 by means of the arms 22 and 23 `and their connecting cables.

To effect tilting or inclining of the stabilizing plane 25, thecontroller lever `16 is moved vertically on its pivotal point in post18. When it is desired to incline the stabilizing plane 25 so that itsrearward edge is elevated, the controller lever 16 is moved downwardlysuch as to the dotted line positions of controller lever 16, stabilizingplane 25 and cables 26 and 29, in Fig. 1. Then it alo is desired to tilttlieistabilizing plane in the opposite direction, lever 16 is movedupj,V

wardly, as will be readily understood.

IVhile I have. illustrated and described the preferred form ofconstruction for carr in@ m invention into effect this is ca al l 2D y 3ble of variation and modification Withoutdeparting from the spirit ofthe invention.` I, therefore, do not Wish to be limited to the exactdetails oi' construction set forth, butV desire to avail myself of suchvariations and modicationg as come Within the scope of.

the appended claims.

Having described my invention What I1 yclaim as'new and desire to secureby LettersI Patent is l. In an aeroplane, a frame; a longitudi-- nallyslotted post pivoted in said frame; a

vrudder plane secured in the slot `of saidl 2. In an aeroplane, a frame;a longitudi-f nally slotted post pivoted in said frame; af rudder planesecured in the slot of said post gl a horizontally disposed slottedshaft jourynaled centrally of and in said post; a stabi;

lizng planesecured inthe slot of said shaft lateral arms on said post;steering cables connected With said arms; and controlling cablesconnected With the rear edge of said stabillzing plane, substantially asdescribed.

' stabilizing lizing plane secured inthe slot of said shaft;

lateral arms on said post.; steering cables connectedvvith said arms;pulleysatthe top and bottom portions of said post; Vand con.

trolling cables over said pulleys and vconnected with the rearedge ofsaid stabilizing plane, substantially as described.

41.-. In an aeroplane,1a slotted verticalpost lrotatably mountedtherein; arudder plane secured in the slot of said vertical post; con#trollingarms on said `vertical post;v a second .slotted vertical postrotativelymounted in the aeroplane; armson saidsecond vertical post;cables connecting the armsA of said s ii'rst vertical post With the armsofc" said second vertical post; stabilizing planes pivotally mounted onsaid first vertical post; a lever fulcrumed in theslot of said secondvertical post for vertical swinging and lconnected torotate said secondlvertical post; and cables'connecting said lever with said planes,`substantially as described.

In testimony whereof- I have signed my name to this specification in thepresence of twosubscribing Witnesses. v
